Problems solved by technology

[0004] At present, in the existing public technology, there are devices and methods for crushing and separating sound-insulating cotton, but there has not been a separation device for sound-insulating cotton, nor has there been a device or method for recycling sound-insulating cotton waste, that is, it has not yet appeared. With regard to the crushing and separation device for sound-insulating cotton waste, there is also a lack of a dust removal and recovery device for the separated sound-insulating cotton waste in the prior art

Embodiment 1

[0032] Such as figure 1 As shown, a sound insulation cotton waste recycling system includes a jaw crusher, a first hammer-type crushing and winnowing integrated machine, a second hammer-type crushing and winnowing integrated machine, a sound-insulating cotton powder slag separation device and a sound-proof cotton powder dust collector device, the outlet end of the jaw crusher is connected to the feed port of the first hammer-type crushing and air-separation integrated machine through the first belt conveyor, and the first hammer-type crushing and air-separated integrated machine is equipped with a first coarse The material outlet and the first A material outlet, the first coarse material outlet is connected to the inlet of the second hammer-type crushing and winnowing integrated machine through the second belt conveyor, and the second hammer The integrated crushing and winnowing machine is equipped with a B material outlet and a second A material outlet. The B material outlet ...

Embodiment 2

[0040] The same as in Example 1, the difference is that the sound-insulating cotton powder and slag separation device separates the first A material and the second A material respectively, so as to improve the separation effect on A material, so that in the recycling process of the sound-insulating cotton waste The purity of the waste in the process is higher, so as to more effectively guarantee the quality of the product after recycling, melting and casting.

Abstract

The invention discloses a recycling method for sound-insulation cotton waste and belongs to the technical field of resource recycling. The method comprises the treating steps: performing first-level crushing on the sound-insulation cotton waste, performing second-level crushing on the sound-insulation cotton waste subjected to the first-level crushing, performing first-level air separation on the sound-insulation cotton waste subjected to the second-level crushing, performing third-level crushing on the sound-insulation cotton waste subjected to the first-level air separation, performing second-level air separation on the sound-insulation cotton waste subjected to third-level crushing, separating the sound-insulation cotton waste subjected to second-level air separation and dedusting the separated sound-insulation cotton. According to the method, the continuous crushing, separation, purification and dedusting on the sound-insulation cotton waste are realized; separated rubber and felt can be recycled, so that the engineering degree is high; the dedusting can be further performed after crushing and separation, so that the cleaning production is ensured, and the environment protection is facilitated; a sound-insulation cotton waste indentifying process is not required; and the method has the characteristics of being large in treating amount, easy in industrial application, low in cost, high in efficiency, simple in structure, free of pollution and the like, and the environment pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of resource recycling, and more specifically relates to a method for recycling sound-insulating cotton waste. Background technique [0002] The main noise source of the outdoor unit of the air conditioner is the compressor part, and the operating noise of the air conditioner compressor is relatively large; in order to reduce the noise of the air conditioner compressor, the noise problem is generally solved through resonance analysis and system matching. At present, the commonly used noise reduction technology for outdoor units of air conditioners mainly realizes sound reduction through the principle of preventing the propagation of sound waves. Existing air-conditioning outdoor units use sound-proof cotton, which is wrapped around the cylinder of the compressor, wrapped around the periphery of the pipeline, and a top felt is installed on the top of the compressor to solve the problem of air-conditioning by a...
